In our recent book, Revolt on the Right, we compiled a list of the most demographically receptive seats in the country for UKIP. This allowed us to rank all seats according to how favourable their populations are for UKIP, using the most recent census data.

UKIP’s ideal seats share key characteristics: they have lots of ‘left behind’ voters who we also know from our research are the most receptive to UKIP and its policies. These seats also have very low numbers of voters who tend to remain resistant to UKIP, including university graduates, ethnic minorities and people in professional and economically secure occupations. This is a useful first exercise in filtering through all seats to find those where if UKIP stood a candidate and knocked on doors they would probably find lots of receptive voters.

Clearly, we are not saying that UKIP will enjoy strong support in all of these seats. It might be that they do not target these seats, or the local Conservative MP has a formidable majority that makes a Ukip insurgency unlikely. In order to find seats that UKIP actually has a chance of winning, you would need to look at both demography and the local political context, such as whether the vote is split across three parties, whether UKIP is targeting the seat and has been recruiting support through local elections.

Take Louth and Horncastle as an example. This is the fifth most UKIP-friendly seat in the country. But it will be incredibly difficult for UKIP to win the seat because of the very large Conservative majority (of almost 14,000). The departure of Sir Peter Tapsell will still make this fight interesting, but even still the seat imposes some obvious barriers for an insurgent party. Alternatively, look at Clacton. This was already the most favourable seat in the country for UKIP before Douglas Carswell defected. Now UKIP has the perfect storm: ideal demography and ideal politics.

So, keeping this important caveat in mind, here are the Top 100 most UKIP-friendly Conservative-held seats in the country:
